IMPROVEMENT IN HAY DERRIGKS.

SPECIFICATION- T0 ALL WHOM IT MAY CONCERN:

Be it known that I, W. l?. SQUIRE, of Paris, in the county of Edgar, and State of Illinois, have `invented a new and useful improvement in Hay Derricks; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art tornake and use the same, reference being had to the accompanying drawings, forming part of this specification, in which?- Figure 1 is a vertical longitudinal section ,of my improved derricli, taken through the line :t m, iig. 2.

Figure 2 is `a rear-end view bf the same, partly in ,section through the line y y, iig. 1,

Similar letters of reference indicate like parts.

My invention has for its object to furnish an improved derrick so constructed and arranged that the hay may be raised and carried forward and at the same time'swung to the right or left for the purpose 'of placing it upon a stack or depositing it in a barn, as may be required, and which may be used for raisingeany` other desired weight; and it consists, rst, in the car pulley in combination with the crane and ropes; second, in the sliding pulley in combination with the ropes and frame of the machine; and third,`in the combination and arrangement of the crane, car pulley, ropes, fixed pulleys, and sliding pulley with each other and with the frame of the derrick, as hereinafter more fully described.

A is the frame of the derric'k; B is the crane, the lower end of the upright part b', of which is pivoted to the crcss'timber a of the frame A', as shown in g. l. To the upper end of the upright'b is securely attached the arm b2 of the crane. The forward part of the arm b? is slotted vertically, as indicated by theV dotted lines vin iig. l. In this slot works the large pulley c of the car pulley C, while the two small pulleys, o2, roll upon the"upper side of the arm b2 on each side of said slot. The pulleys c. and c2 revolve loosely upon the saine shaft, and the face of the pulley c is grooved for the passage of the rope D. The forward end of the rope D, is attached to the weight to be raised; it passes thence over the pulley c of the vcar pulley C, through a guide hole in the upper end of the upright of the crane B, over the fixed pulley F on the rear end of the said arm, and thence` around the pulley e of the sliding pulley E. By drawing upon the rope D, the weight is elevated. To the shaft of the car pulley C, are pivoted the, ends of two short'bars, e3, to the forward ends of which, or to a short bar` or link connecting said ends, s attached the end of the rope Gr, which passes .thence oyer the iix'ed pulley H, attached to the forward end of the arm o2, of the crane B, thence back over the fixed 1, pulley Fon the rear end of the said arm 172; thence down and over the pulley e2 of the sliding pulley E. The sliding pulley E slides back and forth along the cross timbers a2 of the frame A upon three rollers, e3, e4, e5, two of which, e3 Vand e4, roll along the upper side,and one, e5, along the under side of thc timber, ai, as shown in figs. 1 and 2. Upon the rope D, is placed a wooden ball, I, and upon the rope G a ring, d', of` such a size that l the ball I cannot. pass through it. The end of the rope D, to which the power is attached, passes through the ring J, and the ball and ring are so arranged that when the rope D is drawn upon and the weight has been raised toa proper heightl the ring J comes in contact with the 'ball I and the car C and weight are carried forward to the end of the arm bz. The forward end of the arm b2, and with it the weight maybe swung to the right or left, according to the position in which it is desired to deposit the hay or other weight, by sliding the sliding pulley E, in the one or other direction. For convenience in doing this, there may be attached tothe ends of the upper cross piece, as, of the frame A, fixed pulleys, around one or the other of which a rope may be passed, according as it is desired, to swing the crane in one or other direction; one end of said ropel being attached to the rear end of the arm b2, and the other passed around the pulley e6 of the'sliding pulley E, and attached to the draw rope D at such a point that when the weight has been raised to the proper height it mayv be swung to the right or left, as may be desired. By such a construction and arrangement of the parts, the v weight may be raisedycarried forward to the end of the arm b, and swung to the desired position by the single operation of drawing upon the rope D. What I dlaim as new, and desire to secure by Letters Patent, is 1. The car pulley C,`c`onstructed as described, 'in combination with the crane B, and ropes D, G, substantially as and for the purpose set forth. p

2. The sliding pulley E, constructed as' described in combination with the ropes D, Gr, and franieA of the derrick, substantially as and for the purpose set forth and described.

3. The combination and arrangement of the crane B, car pulley C, ropes D, Gr, fixed pulleys H, E, and sliding pulley E, with each other, and with the frame A of the derrick, -suluitantially asrherein described and for the purpose set forth.
